Recliner seating mechanism with seat extension
A mechanism is provided for a seating unit that moves the seating unit between closed, TV, and fully reclined positions. The mechanism allows independent movement of a seat frame, relative to the chair arms and chair back to which the mechanism is mounted. The mechanism thus allows the seat depth of the chair to be adjusted relative to the chair back to accommodate the individual characteristics of the chair occupant.

This application is a continuation of co-pending U.S. patent application Ser. No. 16/244,700, filed Jan. 10, 2019, titled “Recliner Seating Mechanism with Seat Extension,” which claims the benefit of U.S. Provisional Patent App. No. 62/616,864, filed Jan. 12, 2018, titled “Recliner Seating Mechanism with Seat Extension.” These applications are incorporated herein by reference in the entirety.
TECHNICAL FIELDEmbodiments of the present invention relate to recliner seating mechanisms and chairs using them, and particularly to a recliner seating mechanism having a seat extension feature.
BACKGROUND OF THE INVENTIONIn the motion furniture industry, mechanisms exist to move a chair between at least three positions: a closed position, with a footrest stowed and the chair back substantially upright; a TV or extended position, with the footrest extended and the back slightly reclined; and a fully reclined position, with the footrest extended and the back reclined. For certain people, chairs utilizing these mechanisms would find greater comfort if the seat of the chair was moveable, relative to the chair back and/or chair arms.
BRIEF DESCRIPTION OF THE INVENTIONA chair mechanism is provided that allows a chair seat to move relative to the chair back to adjust the depth of the seat. The chair mechanism allows the seat to be adjusted independently of the reclined position of the chair. The mechanism allows the chair to be adjusted between closed, TV, and fully reclined positions, whether the seat is in an extended position or not. The mechanism of the seating unit also drives a seat pitch change from the closed to the extended TV position, and from the extended TV position to the fully reclined position, increasing comfort for the chair occupant.
Additional objects, advantages, and novel features of the invention will be set forth in part in the description that follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention.
The present invention is described in detail below with reference to the attached drawing figures, wherein:
Embodiments of the present invention generally relate to a chair mechanism that allows a chair seat to move relative to the chair back to adjust the depth of the seat. The chair mechanism allows the seat to be adjusted independently of the reclined position of the chair. The mechanism allows the chair to be adjusted between closed, TV, and fully reclined positions, whether the seat is in an extended position or not. The ottoman can thus be opened, and the mechanism reclined, at any point between the seat positions shown in

A mechanism for a seating unit is provided that has a pair of spaced apart first and second base plates, coupled together in spaced relation, each base plate having a front end and a rear end. A pair of mechanisms are included that are operable to move between a closed position and at least a reclined position, with one mechanism coupled to each base plate. Each mechanism includes a seat frame assembly; a back assembly pivotably coupled to the base plate; and a footrest linkage coupled to the seat frame assembly, having an extendable footrest, such that the footrest linkage moves the footrest between a retracted position when the mechanism is in the closed position and an extended position when the mechanism is in the reclined position. The seat frame assembly is coupled to the base plate to allow translational movement relative to the back assembly, such that the seat frame is able to move forward toward the front end of the base plate and backward toward the rear end of the base plate relative to the back assembly.
In some aspects, on the mechanism for the seating unit, the footrest linkage moves with the seat assembly such that the footrest linkage moves forward and backward relative to the back assembly in coordination with the seat assembly.
In some aspects, the mechanism for a seating unit further includes a first actuator coupled between the pair of mechanisms and coupled on one end to a respective back assembly, and on the opposite end to a respective seat frame assembly, such that actuation of the first actuator moves the seat frame assembly with respect to the back frame assembly.
In some aspects, on the mechanism for a seating unit, the seat frame assembly includes: a carrier plate translationally coupled to the base plate, such that the carrier plate is moveable forward and backward relative to the base plate; a seat frame coupled to the carrier plate; and a roller track coupled to the seat frame; wherein the back assembly includes at least a rear seat bracket and a roller support bracket that supports first and second rollers, with the roller track of the seat assembly moveable with respect to the rear support bracket and constrained by the first and second rollers and the roller support bracket.
In some aspects, on the mechanism for a seating unit the end of the first actuator coupled to the back assembly is at least indirectly coupled to the roller support bracket.
In some aspects, on the mechanism for a seating unit the coupling of the carrier plate to the seat frame includes: first and second inclined roller tracks fixed to the carrier plate; a trolley having a first roller coupled to the first roller track, a second roller coupled to the second roller track; and a front pivot link coupled on one end to the trolley near the first roller and coupled on the other end to the seat frame; and a second pivot link coupled on one end to the trolley near the second roller and coupled on the other end to the seat frame.
In some aspects, the mechanism for a seating unit further includes a second actuator coupled on one end to the roller support bracket and on the other end to the footrest linkage assembly, the second actuator operable to move the footrest linkage from the closed position to the extended position.
In some aspects, the mechanism for a seating unit further includes a third actuator coupled on one end to the carrier plate, and on the other end to the base plate.
In some aspects, on the mechanism for a seating unit the first actuator and the third actuator are coordinated in movement to move at the same time and direction.
From the foregoing, it will be seen that this invention is one well adapted to attain all the ends and objects hereinabove set forth together with other advantages, which are obvious and inherent to the structure. It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims. Since many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
